What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
To find out when the boy left school, we need to add 4 hours and 20 minutes to the time he arrived at school.
To add minutes, we need to make sure both times are in the same format. Let's convert the arrival time of 8:15 am to minutes:
So,
8:15am = 8 x 60 + 15 = 495 minutes
Now we can add 4 hours and 20 minutes:
495 + 4 x 60 + 20 = 735 minutes
So the boy left school at 735 minutes after midnight.
To convert this back to a time, we can divide by 60 to get the number of hours and minutes:
735 minutes / 60
= 12 hours (with 15 minutes remaining)
Therefore,
The boy left school at time 12:15 pm.

1. Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
m&A = (2x + 20°
m&B= (4x - 5)
m&C = (3x + 15)°
m&D = (5x + 16)
me= (2x - 2)
What are the angle measures of each vertex of the garden? Show all calculations and work. Keep in mind that
the drawing may not be to scale.
Answer:
a=82
b=119
c=108
d=171
e=60
Step-by-step explanation:
since we can see the figure has 5 sides we can use the interior angle formula 180(n-2) and replace n for 5 getting 180(3) which woukd get us to 540. with this information we know that all the verticals have to equal 540 so we can add the equations together to get
16x+44=540 - subtract 44 from both sides to get x by itself
16x=496 - simplify
x=31
substitute x for 31 in the equations.

Solve the system of equations below. Write your answer as an ordered pair
(x, y).
Solve:
{Y= -3x + 13
{Y= -2x + 1
Answer:
(12, -23)
Step-by-step explanation:
to find x, substitute the value of y into y
-2x+1=-3x+13
collecting like terms
-2x+3x=13-1
x=12
to find y substitute the value x=12 into any of the equation
y=-3x+13
y=-3(12) +13
y= -36+13
y=-23

3/4(12a+8)=31.2 someone please help me solve this:)
Answer:
2.8
Step-by-step explanation:
31.2×4/3
12a+8 = 41.6
12a=33.6
a= 2.8
Answer:
answer is 2.8

3/4=0.75
0.75x12=9
0.75x8=6
9a+6=31.2
subtract 6 from both sides
9a=25.2
divide both sides by 9
a=2.8

Pythagorean theorem :)
Answer:
A^2 + B^2 = C^2
Step-by-step explanation:
Your welcome!
Answer:
x = 13
Step-by-step explanation:
In order to solve this you need to know the Pythagorean theorem:
a^2 + b^2 = c^2
a - 1 side
b - 2nd side
c - hypoteneuse
Step 1: Find the missing side of the triangles
** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**
Solve:
17^2 + b^2 = 19^2
289 + b^2 = 361
361 - 289 = 72
√72 = √b^2
8.5 = b (approximately, to the tenth)
Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:
8.5 + 8.5 = 17
Then you subtract it from the base value: 31
31 - 17 = 13
Therefore, x = 13, as that is the remaining of the base.
